@ButterBean you think I'm in a safe starting place for the H380?
No load data for anything that fast in 257 bee anywhere I could find. I've based my
H4350 load range off abundantly available data. Should be ballpark and for sure safe.
I will say the h380 has a way better case fill than I expected. No worries about detonation or anything. Still ball powder but not near as dense as SUPERFORMANCE, which is crazy dense and as a flattened ball powder packs in even tighter and just doesn't seem to play by any conventional rules at all….kinda like hammers
And after just doing some comparison and research again regarding fill I'm with
@Hand Skills … don't care what hammers have going for them, no way in HECK I'd try cfe223 in this case for any reason under any circumstances
